Hi.
The entity causing the problem:
===============================
@Entity
public class TypeEntity {
@Id
public ... getId();
@Id
@Version
public ... getVersion();
}
The failing query:
==================
pu for xxxx classes TRACE [ejbd 10] openjpa.Query - Executing query:
[SELECT entity FROM TypeEntity entity WHERE ( entity.id = :id ) AND (
entity.version = ( SELECT MAX( sameentity.version ) FROM TypeEntity
sameentity WHERE sameentity.id = :id ))] with parameters: {id=1011}
The exception(s) raised:
========================
javax.ejb.EJBException: The bean encountered a non-application
exception.; nested exception is:
<openjpa-1.0.2-r420667:627158 nonfatal user error>

The workarround:
================
If I remove @Version from getVersion() everything is fine.
The Question:
=============
Bug? Or is it forbidden to use a column tagged @Version in a Query?
Ty in advance,
Dirk
Btw.: I already posted the question on the apache geronimo user list:
